PDC ADVANTAGES
PDC Drill Bits are equipped with Hardened Alloy Steel base material;High performance PDC-Cutters;Carbide and Diamond gauge protection;Carbide/Diamond Shock Studs;Threaded or Plain Carbide Nozzles for Flushing
Above features are subject to changes and modifications according to customers' requirements.
The Diamond PDC drill bit designed to run at high penetration rates even in applications that call for higher blade and cutter counts. Its unique cutting structure layout adds another dimension to bit stability and smooth running by combining the penetration rate potential of traditional "single set" cutter layouts with the life extending features of a "plural set" cutter layout. The result is a bit that runs up to 20 percent faster than conventional PDC bits with minimum bit wear.
Diamond bits work across an extended range of weight on bit, penetrating quickly even at low bit weights in softer rock. When formations firm up, the bits can take added weight with a smooth torque response and maintain higher than competitive rates of penetration. The technology is a departure from traditional plural set bits that require higher weights to drill even in soft rock, and are generally durable, but slow, even in harder rock. Traditional plural set bits also can produce an erratic torque response when taking additional weight.
